Syncrowave 350 just quit

02-15-2014, 02:46 PM

Hi all, I am hoping someone may be able to help, I have an older 350 syncrowave TIG machine and now all runs but no arc, a very weak one is barely visible, foot pedal checks out, coolant is pumping to torch, all connections checked and tightened continuity checks done, does the same in AC, electrode positive or electrode negative, registers 72 volts on the front gauge, points reset, not sure what else except circuit board and I am not sure if that can be tested. Any help would be greatly appreciated. Thank you

OK, I'm a Miller CST tech. I go through the online tech manuals to find the problem and hopefully answer it quickly and correctly. Course that doesn't happen all then time.... Onan engines for example...

Well yes, conduit tends to wear out, water flowing or not, torch will still wear out. I mean you have 72 volts when you hit the pedal of open circuit voltage and very little to no output. So test it in stick mode, that'll tell us right away.

The only leads I have plug into an older buzz box style, I guess I would have to cut off the end and find a ring lug large enough to bolt on. There is no plug style on this machine. Is there a way to test with a meter?
